[Videolib] 16mm cold war films

Hi everyone,
I'm trying to help a documentary filmmaker locate "good" quality 16mm
prints of several anti-communist cold war films made in the US in the
1950's and early 1960's. Titles such as:
Communist Allures to Youth
Communist Blueprint for Conquest
Communist Target Youth
are good examples of what he wants. He's looked at the videos that are
available for the three titles above but he's hoping for better quality
from 16mm.

I remember seeing these or films just like them, published by the US Dept
of Defense or other govt agencies, when I was in school, so the
distribution was probably pretty good. But most libraries have dumped
their 16mm stuff. An OCLC search turned up all three titles in 16mm,
but two are unusable, and not sure of the status of the third. The Getty
holds one title but wants the proverbial arm-and-leg to use any of it.

FootageBank also has some of this material, most of it converted from
film. Anyone familiar with this company?

I've looked at the Moving Image Archives but glazed over at the long, long
list of US archives...is there a way to search by topic? The National
Film Preservation Board is great but doesn't appear to include
documentaries(?) in its focus. I am hoping that somewhere there is a
depository for these old propaganda pieces, with preservation/restoration
being done but I sure can't find one. Any suggestions?
